Bouwmeester, W. (author), Fioranelli, F. (author), Yarovoy, Alexander (author)Incoherent backscattering of mm-waves from natural rough surfaces is considered. A novel method is proposed to determine the statistical properties of surface scattering from range profile measurements. The method is based on modeling the road surface as a grid of uncorrelated scattering elements, described by normalized scattering matrices....journal article 2024

van Trigt, B. (author), Goethem, Jeffrey van (author), van den Bekerom, Michel (M P.J.). (author), Veeger, H.E.J. (author), Hoozemans, Marco (M J.M.). (author)Background: In baseball, repetitive pitching leads to medial elbow injuries, particularly to the ulnar collateral ligament (UCL). To prevent pitchers from UCL injuries, it is important to quantify the response to elbow stress. Repetitive elbow external valgus torque and muscular fatigue induced by repetitive pitching could affect markers of...journal article 2024

Kiliç, Özge (author)This master thesis investigates the influence of flanges on the shear capacity of reinforced non-rectangular members without shear reinforcement. The study adapts the evaluation procedure developed by Yang (2014) for rectangular cross-sections to analyze plates with holes, I-beams and T-beams.master thesis 2023

(author)In various stereological problems ann-dimensional convex body is intersected with an(n−1)-dimensionalIsotropic Uniformly Random (IUR) hyperplane. In this paper the cumulative distribution function associatedwith the(n−1)-dimensional volume of such a random section is studied. This distribution is also knownas chord length distribution and cross...journal article 2023

Rod, J. E. (author), King, Mark (author), Oviedo-Trespalacios, O. (author)Walking is the cornerstone of active and sustainable transport. However, traffic safety concerns among pedestrians could reduce walking behaviour. Safety concerns are generally measured through risk perceptions. Unfortunately, a lack of theoretical development of risk perceptions in walking behaviour research has limited our capacity to identify...journal article 2023

Bouwmeester, W. (author), Fioranelli, F. (author), Yarovoy, Alexander (author)A method for extracting fully polarimetric statistical properties of road surface radar cross sections is presented. This method is subsequently applied to extract radar cross section information from an asphalt road surface. Furthermore, an approach is introduced to synthesise the scattered signal of road surface returns as measured by a radar....conference paper 2023

Roldan Montero, I. (author), Fioranelli, F. (author), Yarovoy, Alexander (author)A novel framework to enhance the angular resolution of automotive radars is proposed. An approach to enlarge the antenna aperture using artificial neural networks is developed using a self-supervised learning scheme. Data from a high angular resolution radar, i.e., a radar with a large antenna aperture, is used to train a deep neural network...journal article 2023

Sonar, Anurag (author)Glass has been widely used in the construction industry since the early nineteenth century. It was most commonly used in the form of a window, which is a flat glass panel. Glass has natural optical properties and is resistant to weather, making it ideal for use as a facade material. Glass’s novel applications in the built environment have led us...master thesis 2022

Zou, P. (author)The submerged floating tunnel (SFT), also called an Archimedes Bridge, is a new type of infrastructure for wide and deep sea-crossings, regarded as one of the alternatives to bored and immersed tunnels and bridges. It is afloat in water employing its buoyancy and a support system to balance its self-weight. However, no prototype SFT has yet been...doctoral thesis 2022

(author)Electroless nickel (Ni) immersion gold (Au), commonly referred to by the acronym ENIG, is the most common protective coating applied on the exposed copper (Cu) traces of printed circuit boards (PCBs). In this work, we elucidate the local corrosion mechanism of the ENIG-Cu system by applying microscopic, surface analysis and electrochemical...journal article 2022
